I build backend systems, and write about what they teach me.

I'm Mohak Tripathi — a backend-heavy engineer and the sole engineer building a multi-tenant B2B product from scratch, shipped to web, iOS, and Android.

Most days I'm somewhere in the unglamorous middle of the stack: multi-tenant data models, GraphQL, database internals, observability, and the work of folding AI into a real product without it becoming a liability. I'm an engineer-founder, which mostly means I own every decision and live with every one of them.

This site is the long version of those decisions. Not tutorials reheated from the docs — the trade-offs I actually weighed, the things that broke in production, and the judgment that isn't already sitting in a search result. I write it down because the act of explaining is how I find out whether I really understood, and because a year from now I'll want to know what past me was thinking.

It's also, deliberately, a small and durable thing. Plain HTML and one stylesheet, no framework, no build step, no tracking. It should load instantly, read well on any screen, and still work in fifty years — the same standard I hold the writing to. If you want to know the rules I'm building it under, they're on the principles page.

What I write about

• Multi-tenant architecture — isolation, data models, and the failure modes that keep me up at night.
• Databases and storage — Postgres in anger, indexing, durability, and migrations that don't lose data.
• Operating a product solo — observability, on-call-of-one, and shipping to three platforms without a team.
• AI in real software — where it earns its place in a product, and where it quietly doesn't.

Building in public

I work in the open as much as I can. The product itself is closed-source for now, but the pieces I can share — experiments, tools, and the occasional extracted library — live on GitHub, and the thinking behind them ends up here.

• GitHub — code, experiments, and works in progress
• The product — the multi-tenant B2B app I'm building (link coming soon)
• Changelog / notes — what shipped and what I learned (coming soon)
